PyTorch 2.5 Release Blog
We are excited to announce the release of PyTorch® 2.5 (release note)! This release features a new CuDNN backend for SDPA, enabling speedups by default for users of SDPA on H100s or newer GPUs. As well, regional compilation of torch.compile offers a way to reduce the cold start up time for torch.compile by allowing users to compile a repeated nn.Module (e.g. a transformer layer in LLM) without recompilations. Finally, TorchInductor CPP backend offers solid performance speedup with numerous en...

The Path to Achieve PyTorch Performance Boost on Windows CPU
The challenge of PyTorch’s lower CPU performance on Windows compared to Linux has been a significant issue. There are multiple factors leading to this performance disparity. Through our investigation, we’ve identified several reasons for poor CPU performance on Windows, two primary issues have been pinpointed: the inefficiency of the Windows default malloc memory allocator and the absence of SIMD for vectorization optimizations on the Windows platform. In this article, we show how PyTorch CPU...

PyTorch Native Architecture Optimization: torchao
We’re happy to officially launch torchao, a PyTorch native library that makes models faster and smaller by leveraging low bit dtypes, quantization and sparsity. torchao is an accessible toolkit of techniques written (mostly) in easy to read PyTorch code spanning both inference and training. This blog will help you pick which techniques matter for your workloads. We benchmarked our techniques on popular GenAI models like LLama 3 and Diffusion models and saw minimal drops in accuracy. Unless o...
